HYDRocAReoN-BURNER.

SPECIFICATION forming part of Letters Patent No. 717,795, dated January 6, 1903.

Application filed July 25', 1901. Serial No. 69.639. (No model.)

To all whom it may concern.'

Be it known that I, FRANCIS M. BAKER, a citizen of the United States, vand a resident of Fond du Lac, in the county of Fond du Lac and State of Wisconsin, have invented a new and Improved Hydrocarbon-Burner, of which the following is a full, clear, and exact description. f

This invention relates to a hydrocarbonburner analogous in some respects to that previously patented by me June 5, 1900, Serial No. 651,226. Y.

This specication is a specific description of two forms of the invention,while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of referenceindicate corresponding parts in all the views.

Figure 1 is a vertical section of the apparatus. Fig. 2 is a horizontal section on the line 2 of Fig. 1. Fig. 3 is a similar view on the line 3 3 of Fig. 1, and Fig. 4 is a sectional view of a modification.

5 indicates the oil-reservoir, which may be double-walled, if desired. The reservoir is supplied with a feed-opening 6, commande by a screw-cap 7.

8 indicates guide-rods in the reservoir, between which a float 9 is vertically movable.

To this float is attached an index-rod 1O,which when the screw-cap 7 is removed will move upward with the float through the opening-6. The cap 7 normally holds the float and rod downward; but the instant the cap is removed the rod will rise, and thus indicate the level of the oil within the reservoir. has a nipple 1l in its top, in which is screwed a thimble 12. This thimble has a tube 14 and a disk 15 suspended rigidly therefrom. The disk is disposed horizontally, and the tube extends vertically and merges into a retort 16, into which extends a wick 17. This wick projects downward through the thimble 12 and into a tube 18, which extends down into the reservoir 5.

19 indicates a rod or strip of metal which extends alongside of the wick 17 throughout the entire length thereof, thus separating the 5o wick at one point from the interior walls of the tubes 18, 14, and'16 and providing a pas- The reservoir sage or space through which gases may pass from the reservoir 5 intothe retort. The retort 16 has a discharge-orifice 20 for the gases generated therein. Sustained on the disk 15 is a cylindrical sleeve 21, which extends vertically and incloses the retort. The sleeve is orificed at its lower portion, as indicated at 22, so as to permit the free entry of air into the sleeve. The top of the reservoir 5 snstains a foraminated cylindrical or barrelshaped casing 23, which is held rigidly in place and formed with an orifice 24 opposite one of the orifices 22 in the sleeve 21. This ortice 24 enables the cup 25 to be reached for the purpose of filling it with oil and permitting the ignition thereof. The cup 25 is fastened to the tube 14 immediately below the retort 16.

Fitting loosely over the sleeve 21 is a collar 26, having spiral threads 27 thereon. These threads 27 respectively engage with projections 28 on the sleeve 21, so that by turning the collar 26 it will be raised or lowered on` the sleeve. Sustained rigidly on the collar by means of brackets 29 is a burner-base 30. -The brackets 29 are extended upward above the, base, as indicated at 31, so as to form sustaining devices for the chimney 32. Garried rigidly by the burner-base 30 is the tubular section 33 of the mixing-chamber, said chamberbeing made up of the section 33 and a tubular section 34, sustained rigidly on the retort 16 and fitting loosely within the section 33, so that said latter section is capable of moving up or down on the section 34, which always stands rigid with the retort and reservoir. Above the mixing-chamber is arranged the burner 35, which is preferably used in connection with an incandescent mantle 36, sustained properly by a rod 37, as usual. Fastened to the retort 16 and projecting upward through the sections 33 and 34 of the mixing-chamber' and through the burner 35 is a rod 38.

The rod 38 is adapted to be heated by the dame of the burner and to transmit the heat thereof to the retort 16, whereby to heat it.

and the oil then ignited, thus primarily heating the retort. This will cause the generation of gas, and as the gas passes out of the opening 2O it may be ignited at the burner 35. The parts being in the position shown in Fig. 1, the upper portion of the rod 38 will be subjected to the action of the heat and it will transmit the heat to the retort, so that the operation of the lamp is thus continued, notwithstanding that the oil may have burned out from the cup 25. It is obvious, of course, that the retort 16 may be primarily heated by means other than by burning oil in the cup 25-for example, a blow-lamp or analogous device. Should it be desired to stop the operation of the lamp, the base 30 should be turned, causing the threads 27 of the collar 26 to act on the studs 28. vate the parts 26, 30, 33, and 35 with respect to the sleeve 21, retort 16, and themixingchamber section 34, and the burner will be raised above the upper end of the rod 33. The heat of the burner will then be no longer transmitted through the rod 38, and the retort 16 will become cool. Thus the generation of the gas therein will be arrested and the flame of the lamp will fail.

In Fig. 4 I have shown the same principle embodied in a torch or blow-lamp which may be used for Various industrial purposes and Vwhich also may be used in connection with the illuminating-lamp shown in Fig. 1-that is to say, as a means of primarily heating the retort 16 in said View.

In Fig. 4 the tube 14 rises from the reservoir 5'Am and carries the wick 17, 161L indicates a chamber serving as the retort, and 35:L indicates the burner-tube, which is fastened rigidly to the walls of the chamber 16a. Within the tube 35n are the telescopic mixingtubes 33a and 34, of which the latter is fastened rigidly in the tube 35iL and the former slidably mounted and connected with afingerrod 39, by which it may be moved longitudinally in the tube 35a. By heating the chamber 16 with a match or any other means gas will be generated therein, and this gas will flow into and through the tubes 33a and 34a to be consumed at the mouth of the mixingtube 33a. Now should the mixing-tube 33a be drawn back to the position shown in the drawings the Haine will come partly within the burner-tube 35a and heat the same. The burner-tube 35 thus provides a continuous metallic heat-conductor from the ignitingpoint of the burner back to the retort 16a, and the heat of the retort will be kept up continuously. To stop the flame, the section 33a of the mixing-tube should be moved forward so as to project beyond the end of the burnertube 35a. The burner-tube being no longer in contact with the iiame it will no longer transmit the heat thereof to the retort 16a. The result of this will be the cessation of the generation of gas or vapor in the retort and the consequent failure otthe dame of the lamp.

This will elee Various changes in the form, proportions, and minor details of my invention may be resorted to without departing from the spirit and scope of my invention. Hence I consider myself entitled to all such Variations as may lie within the scope of my claims.
